comment:

Hemorrhage can be seen anywhere in the bladder. It is commonly associated with inflammation, calculi, or the presence of tumors (
Figure 1
and
Figure 2
). Perimortem hemorrhage can be differentiated by the lack of any concurrent lesions, such as edema, inflammation, or hemosiderin.

recommendation:

Hemorrhage is usually a secondary finding and should not be diagnosed unless it is a major component of the overall lesion and important in the pathogenesis of the lesion. Perimortem hemorrhage should not be diagnosed.
